it's not possible my dear brothers...it is not possible that either cng or petrol.....
lemme clarify a lil...jab mechanic ki samajh mai prob nahi aati to woh yehi kehtey hian
non efi mai yeh prob carburetor ki waja se hoti hia..some times even due to spark plugs as well..
in efi cars...it has to do with the emulator and advancer thing...ya emulator ki timing out ho jati hia jis se yeh prob hoti hia......so always prefer a well reputed local mehcanic and avoid Dealerships
